Sauer Danfoss OMM8 Hydraulic Orbit Motor 151G0040 is a factory-new, high-efficiency rotary drive unit engineered for demanding mobile and industrial applications. Featuring the precise part number 151G0040, this motor belongs to the OMM8 series—acknowledged for robust performance, smooth operation, and versatile integration across diverse hydraulic systems, such as compact excavators, material handlers, conveyors, and hydraulic power units requiring reliable torque and responsive control.
Built on Sauer Danfoss’s proven gerotor/geroller (orbit) design, the OMM8 delivers exceptionally low-speed stability paired with high starting torque and low pulsation. It supports working pressures up to 250 bar (3,625 psi), enabling efficient power delivery even under fluctuating loads. The precision-machined internal components minimize leakage and heat generation, resulting in improved volumetric efficiency, extended service life, and smooth motion control in cyclic-duty environments.
The motor’s robust cast-iron housing encases hardened internal components and sealed bearings, offering resistance to shock, contamination, and vibration. Its compact footprint and standardized SAE mounting flange simplify OEM installation or retrofit into existing systems, while multiple port options and drain configurations support flexible system design. The motor includes integrated relief and check valves, enhancing system protection and broadening circuit design compatibility.
Maintenance is streamlined by Sauer Danfoss’s modular construction; access to critical wear parts—such as gerotor sets and seals—is possible without complete unit disassembly, reducing downtime and total cost of ownership. A unitized end cap and accessible drain ports further aid service tasks. Thorough factory testing guarantees full compliance with performance parameters, including torque, leakage, and overall hydraulic efficiency.
In summary, Sauer Danfoss OMM8 Hydraulic Orbit Motor 151G0040 delivers a powerful combination of quiet operation, durability, and operational safety. With its new condition and OEM-grade quality, it is a dependable choice for engineers, integrators, and maintenance teams seeking a compact yet rugged hydraulic motor for precise rotary motion in challenging fluid power applications.
